# How to calculate the recovered energy?

### How to calculate the recovered energy?

The theoretical power calculated as follows :

1. P(W) = Head(m) x Flow(litres/s) x 9.81.
2. Pe(W) = Head(m) x Flow(litres/s) x 6.86.
3. Flow(l/s) = 1000 x Section(m2) x Velocity(m/s)
4. Rectangular section (m2) = Width (m) x Height (m) of the stream of water.
5. Speed(m/s) = d(m) / t(second)

### How does regenerative braking work?

Regenerative braking : How? ‘Or’ What that works ?

1. by locking the wheels, the engine slows the vehicle without using the brake. …
2. it recharges the battery and significantly increases the autonomy of electric cars (most of the time the autonomy announced by the manufacturers takes into account the regenerative braking).

### How does regenerative braking work?

the regenerative braking is triggered by the action of the driver on the pedal brake : The electric motor of a hybrid or electric vehicle can function in two directions: forwards and backwards. Forward it drives the wheels and backward it recharges the battery.

### How to recover kinetic energy?

The recovery ofkinetic energy can be used by different means of transport and technologies: Formula 1 storeskinetic energy in flywheels since 2009. Thekinetic energy can be transformed into compressed air to serve as a refill for compressed air motors.

### How to brake with a hybrid car?

Driving advice for a hybrid car #2: brake gently. Unlike acceleration, we advise you to anticipate your braking to brake most regularly and as gently as possible (ideally half way on the brake pedal).

### How does starting a hybrid car work?

???? How a hybrid car works ? The car starts with its electric motor. The car will adapt the energy to be used according to your speed and your type of driving. The heat engine and the electric motor work both in order to give power to your car.

### How do SRECs change in price?

Buying and selling SRECs is a lot like playing the stock market – and like with stocks, the price of an SREC changes over time depending on the supply and demand in your state’s market. An oversupply of SRECs leads to lower prices, while an undersupply results in higher-value SRECs.

### What are SRECs and how do I earn them?

As a homeowner, you can earn one SREC for every megawatt hour (MWh), or 1,000 kilowatt hours (kWhs), of electricity your solar panel system generates. SRECs exist because of state regulations known as renewable portfolio standards (RPS), which require utilities to produce a specific percentage of their electricity from renewable resources.

### What is the difference between Rec and SREC?

Like the square-is-a-rectangle logic, SRECs are a type of REC, but specific to electricity that comes from solar technologies.

### What is the difference between ACP and SREC?

Think of an ACP as a cap on SREC prices: utilities don’t have an incentive to buy SRECs at a higher price than the ACP – they would just pay the ACP penalty price instead. How much can I earn by selling SRECs?
